Order of succession

The order of succession is an ordered sequence of people and events in order; and it may mean the passing of royal or other powers.

The "order of succession" may be used in a historical way, such as a list of former leaders. Also, the phrase may mean the pre-planned process through which a leader takes over from another because of death, resignation, or removal

Across the span of centuries, there have been problems with the list and order of succession after St. Peter.[2] For example: During the Western schism in the 14th century, there was more than one pope at the same time. Each had notable international support.[3] Only some are included on the chronology of today's list.[2]

At that time, European leaders had to choose to support one pope or the other.

Across time, there have been difficulties with the list and order of succession after Jimmu.[4] For example: During the Nanboku-chō period in the 14th century, there was more than one emperor at the same time. Each had notable support.[5] Only some are included in today's list

The "order of succession" or "line of succession" is a formal plan which determines who inherits a future role or a position in a hierarchy after death or other cause creates a vacancy or an opportunity for succession.
